A pulse field gradient (PFG) NMR method is used to determine the mean squared displacement (MSD) of the water molecules inside the nanotubes at temperatures below 273 K, where the bulk water outside the nanotubes freezes and hence does not contribute to the proton NMR signal. We show that ...

1H DOSY NMR provides a simple and convenient method to determine both the molecular weight and the solution properties of poly( N -acryloylmorpholine) (PNAM) in various organic and aqueous solvents. This technique is used to measure the average diffusion coefficient D PNAM of a library of PNAM ...
Using advanced solid state NMR techniques, authors reveal how ceramics particles in composite solid electrolytes control lithium dendrites growth in lithium-metal batteries as well as determine the composition and conductivity of the metal SEI.
Two-dimensional rotating-frame nuclear Overhauser enhancement (ROESY) NMR spectra are used to determine the absolute configuration of (+)-diphenyl-phosphine-2,3-dimethyl-7-phenyl-7-phosphabicyclo[2.2.1]hept-2-ene. This diphosphine ligand is obtained from the palladium complex-promoted Diels-Alder ...
NMR Data refers to the information obtained from nuclear magnetic resonance experiments, which, when used alone, is insufficient to determine the positions of all atoms in a biological macromolecule. It needs to be complemented with other structural details such as amino acid sequences, bond lengths...

It has been a great challenge to determine permeability in tight gas sands due to the generally poor correlation between porosity and permeability. The Schlumberger Doll Research (SDR) and Timur–Coates permeability models, which have been derived for use with nuclear magnetic resonance (NMR) data,...
We have used a new solid-state NMR technique--rotational resonance--to determine both internuclear distances and the relative orientations of chemical groups (dihedral angles) in retinal bound to bacteriorhodopsin (bR) and in retinoic acid model compounds. By matching the rotational resonance conditio...
